RAI LWAY-SIG NAL.

SPECIFICATION forming part of Letters Patent No. 600,054, dated March 1,1898,

lApplication fled January 6, 1897.

Z'o @ZZ whom it may concern.-

Beit known that I, HARRY M. ABERNETHY, a citizen of the United States,residing at Elmira, in the county of Ohemung and State of New York, haveinvented certain new and useful Improvements in Railway-Signals; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,Which form a part of this specification.

My invention relates to railway-signals of the class employing therotating shaft carrying visual signals.

The object of the invention is to combine with the rotating shaft of arailway-signal antifriction'devices which will permit the shaft whenturned by the proper mechanism to move freely in its bearings, and thusinsure a prompt movement of the signals carried by said shaft.

My invention is embodied in the mechanism illustrated in theaccompanying drawings,

and its characteristic features will be pointed out in the appendedclaims.

Figure 1 is a vertical section of a signal device constructed inaccordance with my invention, and Fig. 2 is an enlarged sectional viewon the line a; :c of Fig. 1.

The reference-numerals 1 and 2 indicate counterpart sections of theframe of the signal, each provided with the usual bulls-eye lens 3 andsupported in any suitable manner. To the inner side of each of theframe-sections 1 and 2 I secure a disk or plate 4 by bolts 5, and atequidistant points from each other upon the disks 4 are secured three ormore bracket-arms 6 of angular or other suitable form. ATheinwardly-projecting ends of the bracket-arms 6 are each formed with aneye 7 to receive the ends of theshort shafts or gudgeons 8, the oppositeends of which have bearing in the disks 4, as shown. Upon each of thegudgeons Sis mounted a roller 9.

The numeral l0 indicates the signal-shaft extending through an opening11 in the frame-section l and provided with flanged collars 12 and 13,the flanges of said collars being arranged, as shown, to bear againstthe Serial No. 618,205. (No model.)

rollers 9. These collars 12 and 13 are keyed to the shaft 10 and turntherewith and serve as a tread-surface for the rollers. The projectingend 14 of the shaft 10 is adapted to carry a semaphore-signal 15 ofdiamond or other shape.

Arranged upon the shaft 10 within the frame 1 2 is an arm 1G, keyed tothe shaft and carrying at its outer end a colored signal 17, adapted tobe thrown down in the rear of the bulls-eye lamps or raised away fromthe lens by the' movement of the shaft 10.

The shaft 10 is provided with a collar 18 within the frame 1 2, whichcollar is keyed to said shaft and is so constructed and arranged withrespect to the hub of the arm or frame 16 as to warrant the properregistering of the colored signal or signals carried by said arm orframe with respect to the bulls-eye lenses carried by the frame-sections1 2.

The relative arrangement of the rollers and shaft is such that thelatter is equally supported at all points'and freely turns with littlefriction.

It will be understood that a slight departure may be made from thedetails of my invention, as illustrated and hereinbefore described,without departing from the spirit of my invention.

Having thus described my invention, what I desire to claim and secure byLetters Patent is 1. In a railway-signal, the combination with asignal-casing, of a shaft extending through the casing and carryingvisual signals, and roller-bearings mounted on shafts supported bybrackets projecting from the inner sides of the casing, and havingperipheral contact with the shaft.

2. In a railway-signal,the combination with a signal-casing and a shaftprovided with flanged collars, of roller-bearings supported on fixedshafts projecting from the sides of the casing and bearing against theflanges of the collars.

3. The combination With the casing or framing of a railway-signal, ofradially-arranged bracket-arms secured to the inner sides of thesections of the casing and projecting in Wardly therefrom, gudgeonssupported by said brackets, rollers mounted on said gud- IOO geons, anda shaft passing through the casing or framing, said shaft carryingvisual signals and supported by said rollers, substantially as shown anddescribed.

4. The combination with the Casin g or framing of a railwayfsignal, ofdisks or plates secured to the inner sides of the opposite sections ofthe casing, radially-arranged brackets secured to said disks or platesand projected inwardly therefrom, gudgeons having bearing in saidbrackets and disks, rollers mounted on said gudgeons,a signal-shaftpassing through the signal casing or framing and supported by therollers, said shaft being provided With flanged collars against whichthe rollers bear and with visual signals, substantially as described andfor the purposes set forth.

5. In a railway-signal, the combination with a signal-shaft carrying avisual signal and flanged collars, of roller-bearings having peripheralcontact with said collars and bearing against the flanges thereof, and acollar keyed to the shaft intermediate of said iianged collars forregulating the movement of the co1- cred-signal frame, substantially asdescribed.

6. In a railway-signal,the combination with the lenses, of asignal-shaft carrying a visual signal, roller-bearin gs having peripheral coutact with the collars, a colored-signal frame supported by saidshaft, and a collar keyed to said shaftadapted to regulate the movementof the colored-signal frame with respect to the lenses, substantially asdescribed.

In testimony whereof I affix my signature in presence of two Witnesses.
